Hi fellow calgun members!

So for the most part I am very much into .22lr fire arms,
shotgun clay shooting. But I never thought I would find myself
attempting the rifle scene, I've had several people told me buying a rifle is almost unavoidable...

so recently I just bought a s&w mp15-22 and I absolutely love this thing,
but I had this thought for quite some time now..

How much would an entry level ar15 9mm cost?
Why 9mm? no real reason, I guess you can say ammo cost and what
have you... but I guess I just want a ar15 9mm.

can anyone point me the right way and give me some tips on
a proper build? or if there is a general ar15 9mm build that
most people use?

I dont know anything about the ar15 scene...so any help would be great!!

thank you so much

and God Bless!

You're in Orange County?
Stop by RifleGear man. Great shop and they have plenty of information and 9mm AR stuff.
They have 9mm uppers and with one of those you can either get a normal AR lower (5.56) with a 9mm conversion kit OR they also sell a machined/dedicated 9mm lower.
Good stuff man.

Check it out or stop in.

9mm dedicated AR lower for use with AR upper. (http://www.riflegear.com/p-631-cmmg-mk-9-dedicated-9mm-lower.aspx)

9mm in an AR is like putting a 4cyl in a Corvette.

Exactly. You get better gas mileage. :)

Use an Olympic Arms upper becuase it works on a regular rifle lower with no special parts unlike the others which need special a special hammer and buffer.

LOL... yea, most everything has its place. i use my 9mm AR for steel challenge competitions where .223 is not allowed.

A 9mm ar will run you a little bit more than the 556 big brother. A reasonable no frill one will run you about 1200 as stated above. A cmmg ramped carrier is nice so if you do decide to get a 556 upper, you can keep the same lower without changing out the hammer and slap it on. Normally the dedicated 9mm carrier requires a different hammer.

I thought 9mm carriers needed non-notched hammers which will work just fine with regular carriers.

Meaning if your lower will work with a 9mm it will work with a 5.56

That 9mm is going to cost you more initially.

That 9mm will recoil similiarly to 5.56 since the 9mm operates on direct blowback, while the 5.56 unlocks the breach.

That 9mm will have a very limited range compared to the 5.56

That 9mm will have very limited terminal performance (for appliactions like hunting/self defense) compared to 5.56

You already have a .22lr for cheap practice.

Just being a friendly devil's advocate so that you know what your getting into and don't make a foolish mistake. Having said all of that, I have a 5.56 and .22lr ar, and some day I think either a 9mm or 7.62x25mm upper will work its way into my life.

Why not just go for a 5.45 x 39 upper, more fun then a 9mm and cheap to shoot 190 for 1080rds surplus.

Putting 9mm in an AR reminds me of the 4 cylinder SVO Mustang form the Mid 80's. It had a higher top speed, barely matching the 5.0 0-60 times.

The 9mm AR is a lot of fun... if you build it yourself, you can be out $850.

Yeah, but unfortunately they're made by Olympic Arms and tend to be utter crap.

If you live in OC, 9mm is nice because you can go pop off a couple shots up the street at the indoor range.

We don't have any rifle ranges that close.

OT: How much "fun" is shooting a rifle in an indoor range? Isn't it kinda easy?

Ramping a Colt style 9mm Bolt: Why??

Although a Colt/Rock River 9mm upper will work with most hammers, it really was intended to be used with the Rock River 9mm hammer. The hammers are reset in only 1/2" of bolt travel, which puts a considerable stress on both the hammer and the hammer pins. Although it will not ruin a gun immediately, on a long enough time scale, espeically on full auto guns, this constant beating can wear on the lower and in some instances will "egg out" the hammer in holes. The easy solution to this is to "ramp" the bolt, where the ramped area is increased in length (a shallower slope) thus increasing the reset distance to about 1 1/4" or so, and more than doubling the reset time of the hammer, thus lowering the impact forces on the lower, pins, etc.

Mine has thousands of rounds though it without any problems. What went bad on yours?

I've never owned anything from Olympic arms, but have seen their shoddy work. They are a bottom-of-the-barrel manufacturer that pays no attention to standards or quality. Period.

Your anecdotal evidence does not mean that all Olympics are awesome guns.
